Well first, never execute arbitrary python code unless you know what's it doing becaue it could be malicious code. Fortunately, I do know here, spoiler alert...

This is a form of simple code obfuscation using my emojify tool. Running this code in the python interpreter/script prints "Happy holidays" using ascii art from here .

Finally, Happy holidays, to all the up voters, the down voters: the commenters and the close voters :)
